HENRY H. NEWBY, or SAN QUENTIN, camroni na SURF-BOARD,

I Specification of Letters Patent.

Application filed December 14, 1e17, Serial No. 207,131. Renewed May 10,1919. seat-1 m. 296,056."v

To all whom it may concern:

Be it known that I, HENRY H. NEWBY, a citizen of the United States,residing at San Quentin, in the county of Marin and State of California,have invented new and useful Improvements in Surf-Boards, of which thefollowing is a specification.

This invention relates to a surf board which is in the nature of acatamaran through the use of which the pleasure de- Y Y rived from surfboating and bathing-may not only be materially increased but suchboating and bathing rendered safe to inexperienced persons. a

The primary object of the invention is to provide an inexpensive deviceof this character wherein provision is not only made for permitting theperson using the device to propel himself over the surface of the water,but to so construct the device that the person lying thereon may freelyuse'his feet and legs for controlling the direction of travel of theboard.

Another object of the invention is to provide the board with a propellerwhich has associated therewith mechanism of novel construction throughthe operation of which the propeller may be set in motion to cause theboard to travel over the surface of the water. I

A further object of the invention is to provide a device of thischaracter wherein a plurality of floats are attached to a board which isrecessed upon opposite sides'adjacent one end of the board in such amanner that a person lyingv thereon may have free use of his or her feetand legs for the steering of the board over the surface of the water.

A further object of the invention is to provide hangers of novelconstruction for the propeller operating mechanism associated therewith.

With these and other objects in view, the invention resides in the novelcombination and arrangement of parts, which will be hereinafterdescribed and particularly pointed out in the claim. Y

Y The preferred embodiment of the invention has been illustrated in theaccompanying drawings, although no restriction is necessarily made tothe precise detalls of construction therein shown, as changes,alterations, and modifications within the scope of the claim may beresorted to when desired.

V Fig. 4 1s a vertical transverse section. on a the-line 4-4 of "Fig. 1.Y

Like characters of reference denote'corre sponding parts throughout theseveral views 1n the drawing. 1

Referring nowto the drawings when constructed in accordance with theinvention includes a plurality of floats 5 which are preferably arrangedin/p'airs and with forcement therefor;

A board 10 rests upon the ribs 9 of the floats 7 and has secured to thesides thereof the ribs 9 upon the floats 6 which are of greater lengththan the floats'7. Secured to the bottom of the board 10 aretransversely extending plates 11 on which are formed spaced ears 12arranged in pairs with each pair of ears having passed therebetween arib on one of the floats 7 to which the ears are secured in a suitablemanner. One of the plates 11 which is arranged in advance of the floatshas connected therewith and with the floats 6 struts 13 by means ofwhich the portions of the floats 6 which extend beyond the floats arebraced.

The board 10 is cut away upon opposite sides adjacent the rear endthereof to provide recesses 14, so that a person lying upon the board 10may allow his feet to extend into the water for guiding the board 10. Itwill be noted with reference to Fig. 1 in the drawing that the shape ofthe recesses 14 are such that the person can freely move his legs forthe purpose stated and that the recesses provide the board 10 at itsrear end with an extension 15 upon which'the feet may be placed when notemployed in guidingthe board 10. Extending longitudinally Patented Dec.9, 1919,. 5

in detail I the letter A designates a surf board which of the board 10between the recesses 14. and the forward end of the boardare hand rails16 which have connected therewith straps 17 by means of which the personemploying the device may strap himself thereto if desired, it of coursebeing understood that the hand rails 16 also serve as means by which theboard may be carried from place i to place and to which a person mayhold when launching the board or when coasting on the waves. If desireda pneumatic cushion may be mounted upon the board 10 adcomprising a partof the frame 18 is a propeller shaft 20 to one end of which is fixed apropeller 21. The other end of the shaft 20 has fixed thereto a pinion22 which is engaged by the teeth on the gear wheel 23 fixed to a shaft24. mounted to turn in hangers 25 on the board 10.

The shaft 24: has fixed thereto a pair of ratchet wheels 26 and hasmounted to turn thereon a pair of arms 27 which are arranged adjacentthe wheels 26 and with each arm having fixed thereto a dog 28 which isyieldably held in engagement with the teeth on a ratchet- Wheel 26 by aspring 29. Each of the arms 27 is pivotally connected with one end of alink 29 the opposite end of which is pivotally connected with the lowerend of the lever 30 which extends above the board 10 through a slot 81therein and is suitably mounted for swinging movement in boxings 32, onthe board.

Through the provision of the levers 30 it will be apparent withreference to the draw.- ing that when the levers are swung by a personlying upon the board 10 the rotation of the shaft 20 may be accomplishedfor the propulsion by the propeller of the board 10 over the surface ofthe water, while the occupant of the board may steer the same in anydirection desired by letting one of his feet hang Within the water uponwhich the board is supported.

From the foregoing description taken in connection with the accompanyingdrawing it is apparent thata surf board has been provided which thoughinexpensive of construction is capable of rendering surf bathingcomparatively safe and enjoyable for inexperienced persons.

Having thus described the invention, What is claimed as new, is

A device of the class described comprising a board, propelling meanscarried thereby, transversely extending plates on the bottom of saidboard a pair of spaced floats, ears on said plates, ribs on said floatspassing be tween and fixed to said ears, and other floats of greaterlength than the firstqnentioned floats having ribs thereonfixed to saidboard at opposite sides thereof.

In testimony whereof I affix my signature.

HENRY H. NEWBY.
